Overview of traffic flow hybrid ANN forecasting algorithm study

ANN is the core of the 2^rd and 3^rd generation traffic flow forecasting algorithm. In order to master the traffic flow forecasting tendency comprehensively, this paper studied every kind of hybrid artificial neural network forecasting algorithms in detail, including ARIMA ANN model, fuzzy ANN model, GA ANN model, Chaos ANN model, Wavelet Analysis Model, Principal Component Analysis ANN model and Particle Swarm Optimization ANN model. First it abstracted those algorithm flows into common form, then made general network structure, and analyzed every kind network´s virtues and shortcomings, at last, proposed traffic flow prediction developing tendency in future.
